TORS OF WEFT-REPLENISHING LOOMB.

'latcntedOct. 8, 1912.

type shown and described in U. S. Letters Patent, No. 972,722, in which a fillingdetector or feeler feels through an opening in the front wall of the shuttle to engage with the filling on the bobbin in the active shuttle on every other forward movement of the lay, and on the substantial exhaustion of filling operates mechanism to cause the weft. replenishing mechanism to supply a fresh bobbin in the usual and well known way. Said filling detector or feeler comprises a slide, which on every second forward movement. of the lay is yieldingly held against; the filling on the bobbin. and moves therewith toward the front of the loom as the lay beats up, to cause the pivot point of an oper ating lever to be withdrawn. as long as there is a sufficient amount oi titling on the bobbin. Upon the substantial exhaustion oi filling on the bobbin, a rocking lever will remain in its inoperative position and cause a pivot point to remain underneath an operatmg lever of the weft replenishing mechanism, and a bobbin will be dropped from its compartment to the discharging end of the magazine, all in the usual and well known way, and as fully described in the Letters Patent, No. 972,722, above referred to.

The object of my invention is to improve upon the construction of the filling detector or feeler, and more particulm-ly to provide and to combine therewith, supplemental mechanism or means, which on the cngagement of the feeler with a full size bobbin, or a substantially 'full size bobbin, will lock and'hold the fceler out of engagement with the filling on the bobbin, and thus prevent the :teeler from engaging the filling every other pick, as the loom operates. The filling detector or feeler remains locked and held in it; inoperative position, as the loom operates, until upon the change of the shuttle boxes. through intermediate connections therefrom to a sliding rod, said rod causes the filling detector or feeler to be unlocked, and enables it to feel for another bobbin in the activeshuttlo from another box cell. If the filling on this bobbin has been drawn oft sutliciently, and the size oi the bobbin, where the 'teeler engages the filling, has become substantially diminished, the feeler remains unlocked and engages with the filling in the usual way, to detect the substantial or ractical exhaustion of the filling on the be bin. But it'. the bobbin in the active shuttle from another box cell is full size, or substantially full size, it will cause the filling detector or footer to be again locked, and held inoperative until the next change of drop shuttle boxes takes place.

My invention consists in certain novel features of construction of my inu'n'ovements as will be hereinafter fully described.

I have only shown in the drawings a filling detector of the type above referred to, and a detached portion of a stationary magazine, with my improvements combined therewith, sullicicnt to enable those skilled in the art: to understand the construction and operation thereof.

Referring to the drawings:---Figure 1 is an end view of a detached portion of a weft replenishing loom, with my improvei'nents combined therewith, looking in the direction of arrow a, Fig. 3; the lay beam and shuttle are shown in section. Fig. 2 shows some of the parts shown in Fig. l, in a different position; some of the parts shown in Fig. 1 are not shown in thistigure. Fig. 3 is a front view oi the parts shown in Fig. 1, looking in the direction of arrow Z1, same figure: also shows a portion of-the selecting mechanism, not shown, in Fig. 1; some of the parts in Fig. 1 are not shown in this figure, and, Fig. 4 is an inner end view of the parts shown in Fig. 3, looking in the direction of arrow 0, same figure.

In the accompanying drawings, 1 is a stand secured to the. breast beam, not shown;

said stand 1 has rigidly connected thereto the inner end 2 of a stationary magazine. The stand 3 is secured to the stand 1 by bolts 4, and has a stud 5. carrying a bushing ti. secured thereon by a nut 7, see Fig. 3, to adj ustably receive the fecler bed or stand 8, which is clamped on the bushing (l by a bolt 9, and rests at its front end on an adjusting on the bobbin 14 in the active shuttle 15 on the lay 16. a v

The feeler slide 11 is yieldingly pressed against the filling-by an expansion spring,

not shown. ,A connector rod 17 is attached at one end to the feeler slide 11 and at its other end is pivotally connected to the uper end of an upright lever 18, which has its ub 18' fast on one end of a shaft 19, loosely mounted in bearings 3 and 3 on the stand 3, see Fig. 3. A helically; coiled torsion spring 20 encircles the shaft 19, and has one end connected to the bearing 3, and its other end to'a collar 21 secured on the shaft 19 by a screw 21'. The torsion spring 20 acts to cause the shaft 19 to rock, and the lever 18 to move with said shaft in the direction of the lay. On the opposite end of the shaft 19 is secured the hub 22 of an upright lever 22, see Fig. 3. The upper end of the lever v 22 is pivotally connected to the outer end of the horizontally extending rod 23, see Fig. 2; the inner end of the rod 23 is loosely guided in the stand 3, and the forward end of said rod extends into an opening or slotted portion 3', and is adapted to form the pivot point for the end of the operating lever 24, seeFig. 3, of the selecting mechanism of'the magazine.

A rocking movement is communicated to the lever 24 by a cam and lever on the loom, not shown, through a vertically extending connector 25, which has a rod head 26 thereon, guided in a boss "3 on the stand 3, see Fig. 3. The upper end of the rod head 26 is yoke shaped, and pivotally connected to the center portion of the lever 24. The

- outer end of thelever 24 has pivotally connected theretmthe rod head 27 on an upwardly extending rod or connector 23, see Fig. 3. The upper end ofthe connector 28 is pivotally connected to a-stud 29 on a lever- 30, which hasits hub 30 loosely mounted on arod 31, see Fig, 4, and is prevented I to the rod 31, to cause it to be moved longi from having a longitudinal movement on said rdd by two lugs or bearings 2 on the magazine 2. The rod 31 is connected at its opposite end, through intermediate connections 'not shown, with the drop shuttle boxes on the opposite end of the loom. The raising and lowering of the drop shuttle boxes will impart a reciprocating.movement tudinally, according to the number of the shuttle boxes, and in this instance to cause said rod to have four different positions longitudinally.

The lever 30 haslugs30 thereon, see Fig. 3, to loosely receive the spring actuated bolt 32, which, through the action of a helically coiled expansion spring 33, mounted on the reduced portion of said bolt, bears against thestand 1 when the lever 13 is in a horizontal position, to prevent said lever from moving downwardly, unless through the action of the lever v24.

All of the above mentioned parts may be of the usual and well known construction,

as fully shown and described in Letters Patent, No. 972,722, above referred to, and also in Letters Patent, No. 1,030,748.

I will now describe my improvements'in T locking mechanism for the titling detector or feeler. v

The upright lever. 22 is provided at its upper. end, in this instance on one side thereof, with a roll 34 on a stud 34; said" roll 34 is adapted to travel along the upper edge of'a horizontally extending lever 35, see Fig. 1. The'lever 35 has its hub 35 pivotally mounted on a stud 36 on -the stand 3, and has the inwardly extending arm 35", which has connected thereto the upper end of a helically coiled contraction spring 37, 90' i see Fig. 2. The lower end of the spring 37 has a chain or flexible connection 38 conv nected thereto, which leads to a cam lever on the loom, not shown; the movement of, said cam lever, through the connection 38,. aets-to increase or diminishthe action of. the spring 37 on the lever 35, at the desired time, that is when the roll'34, through the action of a full bobbin, is carried be.- yond the center of the cam projection 35,

at which time the action of the cam, not

shown, causes a tension on thefoonnection 38- and spring 37, to move the outer end-of the lever 35, and through the cam projection 35 cause an additional outward movement of the roll 34, to cause it to enter the recess or notch 35", hereinafter described, and

cause the fecler device tomove away fromthe bobbin. The outer end of the lever 35 has an extension 35 thereon, which forms a recess or notch 35", see Fig. 2,

adapted to receive the roll 34, if the lever 22 has been moved to its extreme outward position (see Fig. 1), through the rocking of the shaft 19 on the backward movement of the lever 18, by the engagement of the feeler slide 11 with the filling 13 on a full size, or substantially full size .bobbin 14. The spring 37, through the arm'35", moves upwardly the arm 35, and causes the lever 22 to be locked and held in the position 'shown in Fig. 1, and the feeler slide'll and fecler 11 are leckcd and held in their outer position. 1

The lever 35 has a cam projection 35 thereon, of angular shape, which, on theupward movement of the lever is adapted to engage one of the outer inclined surfaces, or enter one of the notches 30 in thelower ,eud of an upright arm or lever 39, see Fig.

mounted on a stud 40 on the stand 1. A lug or extension 39' on the hub 35) is adapted to adjustably hold, by a screw 41, the lower portion of an upwardlyextending arm 42. The arm 42 has the upper cngaging end 42 thereon, extending in the path at and engaged by the reciprocating sliding rod 31, see Figsi 1 and 2. Ahclically coiled contraction spring 43, which has one end connected to a lug 39 on the lever 39, and its other end connected to a. stud it on the stand '1, acts to hold the end it? on the lever ii in engagement with the sliding rod 31. 'lhrough the movement of the drop shuttle boxes and the reciprocating movement of the rod til, a rocking movement is imparted t the levers if! and 3?), which causes, through the notches 35) on the lower end oi the lever 39 engaging the triangular cam extension 35" on the locking lever 35, said lover 2-35 to be depressed, to unlock and release the lever 22, the rock shaft 19, and lever 18, and the feeler slide 11 and :tecler ll, until another bobbin of full size. or of subslz'intially full size, locks said t'celc and footer slide-ll, as above described.

"The operation of my improvements in locking mechanism for the filling detector or l'cehrrwill be readily understood from the drawings in connection with the above dc scription, and brietl'y is as follows Tn case of a full size, or a substantially full size bohbin in the active shuttle, as shown in Fig. '1, when the lay advances, the filling on the bobbin engages with the end 11 of the feele-r slide 11 and moves backwardly said t'eeler slide and the lever 18, and rocks the shaft 19, and moves outwardly the lever 22, until the roll 34 on said lever 22, is in position to enter the notch 35 in the lever 35). The lever 35, through the action oi the cam lever, not shown, and the connection 3%, spring 37, a nd'arm 35", raises the lever and causes the roll 34 to move outwardly, and engage with the notch 35*, and holds the lever 22, the lever 18, and the feeler slide 11 in their outward position. On a change of the shuttle boxes, the movement of the rodBl to the left in Fig. 2, will move the lever 35) at its lower end, against the action of the spring 43, from the position shown in Fig. 2 to the position shown in Fig. 1, or to an hitermediate position. The movement ot' the rod 31 in the opposite direction will allow the spring 43 to act to move the lever 39 in an opposite direction, that is from the position shown in Fig. 1 to the, position shown in Fig. 2. The movement of the lever 39 will cause, through the engagement of the lower end of the lever 39 with the cam extension 35" on the lever 35, said lever 35 to be depressed, against the action of the spring 37, to release the roll 34 from the notch 35 in said lever, and allow the torsion spring- 20 to act to cause the rocking of the shaft 19, and the movement of the lever 22, and the lever 18, and the teeter slide 11, toward the lay, so that the tccler slide or detector will be in operative position to engage the bobbin on the forward movement of the lay. [1 there is a snliiciont amount of filling on the bobbin to move the feeler slide back far enough to rock the shaft 19, and move the lever 22 far enough to allow the roll 34 on the lever 22 to engage the notch 35* in the lever 35, then said lever '22 and the lever 1S, and the teoler slide ll, will he again locked in their outward position, but if there is not enough filling on the bobbin to move said parts to the position stated, then the feeler slide 1.]. will be moved into operative position, to enter the active shuttle on every other forward movement of the lay, to detect the substantial exhaustion of filling on the bobbin therein, in the usual way. After the :feeler slide has detected the substantial exhaustion of filling on the bobbin, it is retracted or moved. backwardly preparatory to the insertion of a. full bobbin-in the shuttle in any suitable manner, preferably by means of an arm connected with the transferrer arm, which, on the downward movement of the transt'crrer arm to transfer a full bobbin from the magazine into the active shuttle, engages a projection on the feeler slide, and moves it backwardly to cause the feelcr to be moved away from the shuttle, such a mechanism is shown in the draw ings of the U. S. Letters Patent, No. 972,722, above referred to.

it will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

fl. Tn a wet't replenishing loom, a feeler or detector to contact with the filling on the filling carrier in the active shuttle, to determine the amount of filling thereon, means to lock said tecler in itsinoperative position, and means, operative through connections to the drop shuttle box mechanism, to unlock said feelcr.

2. In a well replenishing 100111, a feeler or detector to contact. with the filling on the filling carrier in the active shuttle, to determine the amount of filling thereon, means,

3. in a weft replenishing loom, a filling iccler, means to cause the same to contact with the filling on the filling carrier at pr determincd periods, means, cooperating with tho filling on the filling carrier, to move said lceler out of a position to contact with the filling, means to lock said feeler in its inoperative position, and means, operative through connections to the drop shuttle box mechanism, to unlock said felerand to allow it to return to its normal operative position.

4. In a weft replenishing loom, a feeler or detector to contact with the filling on the filling carrier, to determine the amount of filling thereon, means, including a movable cam surface, and connections thereto, to cooperate With the filling on the carrier to move said feeler out of a position to contact with the filling, means to lock said feeler in its inoperative position, and means, operative through connections to the drop shuttle mechanism, to unlock said feeler.

I 5. In a Weft replenishing 100111, a feeler or detector to contact with the,filling on the filling carrier, a rockshaft havingan'arm thereon, connections from ,said arm to said feeler, a second arm on said ifioc'k shaft, an oscillating lever having a cam 'jsurface thereon at one end, means at ,the szime end of, said oscillating lever to coope ate with and lock said second mentioned arm, connections from the other end of said oscillating lever" to a cam, to operate said leverf in one direction, and means cooperating with said cam surface on said lever, to operate said oscillating lever in the opposite-direction.
